Application filed May 6, 1913. Serial No. 765,837.

To all whom it may concern Be it known that I, CHARLES J. Gnrvnnr, acitizen of the United States, and resident of the borough of Bronx, inthe county of Bronx and State of New York, have invented certain new anduseful Improvements in Pipe-Calking Machines, of which the following isa specification.

This invention relates to pipe calking machines. Its object is theproduction of a machine which can easily be placed in operative positionaround the cylindrical surface of piping andthe like, to calk the jointsthereof. Means are provided to connect the machine with piping ofdifferent diameters and to tilt the machine during its operation toeffectively calk the joints of the piping.

1n the accompanying drawings Figure 1 represents a top plan view of amachine exemplifying the invention in operative po sition on piping witha bell and spigotjoint, Fig. 2 shows an elevation and partial section ofFig. 1, on the line 2, 2, Fig. 3 is a left hand side view of Fig. 1,showing the machine in two operative positions on two diameters ofpiping in section, Fig. 4 represents a top plan view of a fragmentary'portion of the track for the machine witha fragmentary portion ofpiping, Fig. 5 shows a section of Fig. 4 on the line 5, 5, Fig. 6represents a right hand view of a figure like Fig. 5 when notsectioned,'Fig. 7 shows a partial section of lFig. 2 on the line 7, 7,and Fig. 8 represents a fragmentary top plan View of the truck frame ofthe machine with some details.

The spigot end of a length of piping is shown at 20 in place with thebell 21 of an accompanying length of piping.

A track comprises four quadrants 22, 23, 24, 25 of channel irons. Thequadrants 24 and 25 carry each a hinged turn-buckle member 30, and thequadrants 22, 23 carry each a hooked turn-buckle member 31. Each member30 is connected to its accompanying member 31 by the right and lefthanded screw 32. The pair of quadrants 22, 23 and 24, 25 are connectedby a linked locking device, each of which comprises a pair of links 36,fulcrumed on a pin 37 extending from brackets 38 fastened respectivelyto the quadrants 23, 24. A pair of links 40 are hinged on pins 41extending from brackets 42 fastened respectively to the quadrants 22,25. A link 45 connects each of the links 36 and 40, and a pin 46connects the links 36 and 45. A nose 49 extends from the bracket 42 andthe pin 46 locks therewith, when the quadrants are in position on thepiping. The screws 32 serve to take up lost motion between the track andthe piping.

Separators 50 and 51 are riveted to the inner faces of the quadrants.Reinforcing strips 52 are fastened to the quadrants and set screws 53extend. through the strips 52, the quadrants and the separators 51 topinch the piping. One pair of the separators 50 extend beyond one of thequadrants and supports the foot 55 of a bracket 56. A spindle 57 isjournaled in the bracket 56 and which has fastened at one end thereofthe sprocket chain wheel 58, and at the other end the balance wheel 59with the operating handle 60. To the quadrants 22, 23, 24, 25 arefastened on the inside faces of the flanges thereof, the guide channelportions 65. On the outside faces of the opposite flanges of the saidquadrants are fastened the guide channel portions 66. Notches 67 and 68are respectively formed in the channel portions 66 and 65, to permit themovable portion of the machine to be located in operative position.

A truck frame 70 has formed with its front end a pair of upper guides71, and a pair of lower guides 72. The said frame has adjustably pivotedthereto by means of the pins 73, the front journal box frames 76, thathave each formed therewith a rib 77. Pairs of ribs 80 are formed atopposite sides of the truck frame and straddle their accompanying ribs77 so that bolts 85 can connecta perforation in the ribs 77 withperforations in their accompanying ribs 80, to enable the box frames 76to be tiltedk in different operative positions for different diametersof piping. 1n each journal box frame 76 is located a pivot bolt 86, onwhich is journaled a guide roller 87 that engages the channel portions66. Guide rollers 88 are journaled on pivots 89 extending from the rearportion of the truck frame 70, and can surface of one of the flanges ofthe quadbear against the innerv i perforations 95 extend calking chisel1.52

rants 22, 23, 24, 25 of the track. To the truck frame 70 is alsoadjustably pivoted the rear journal box frame 90, by means of a pivot91. The frame 90 carries a pivot bolt 92, on which is journaled the rearguide roller 93, that registers with the guide channel portions 65.

A pair of ribs 94 having a plurality of from the truck frame 90, and arib 96 with a perforation extends from the truck frame 70. A bolt 98connects the perforation 95 with the perforations in the rib 96, tolocate the guide roller 93 in different positions. With the truck frame70 is formed the cylindrical seat 99 with the flanges 100. A bracket 101is supported on the flanges 100 and secured by bolts 102. An adjustingair cylinder 103 with the heads 104, 105, and the air inlet port 106 islocated upon the seat 99, and held in place by the bracket 101. An airinlet pipe 107 with a three way cock not shown leads to the port 106. Apiston 110 in the cylinder 103 has pinned thereto the piston rod 111that is guided in the head 105. lA cup leather packing 112 is fastenedto the piston 110. A spring 113 bears between the head 105 and theVpiston 110. The piston rod 111 carries a spring bracket with the eye 114having the guide flanges 115 and legs 116. The latter are connected tothe legs 117 of a second spring bracket having the eye 118 with theguideflanges 119. Bolts 120 connect the legs 116 and 117. The flanges 115register with the upper guides 71 of the truck frame 70, and the flanges119 register with the lower guide 72 thereof. A collar 120a is formedwith the piston rod 111. A spring 125 encircles the rod 111 and bearsbetween the collar 120al and eye 114. Set screws 126 are in threadedengagement with the eye 114 and pinch the rod 111.

Upon the bracket 101 is fastened a rack 130 by means of the bolts 131.rlhe ends of said rack have formed therewith the eyes 132, that engage alinked chain with the links 133 and rollers 134, that are joined withsaid links by means of the pins 135. The pitch of the rack and chain arethe same, and register with the sprocket chain wheel 58, and with therotations of the said wheel, the rotative portions of the machine arerevolved around the piping, thel chain extending around the latter. Legs140 extend from the rear portion of the truck frame 70 and supportpivots 141 on which are journaled, the spool 143 for lead-'wool 144, andthe spool 145 for yarn 146. Guide funnels 147, 148 extend from the frontend of the frame 70.

' An automatic calking tool 150 is clamped in the eye 118 and set screws151 in threaded engagement with said eye pinch the calking tool. Thetool 150 carries the reciprocating that enters the clearance spacebetween the spigot 20 and the bell 21 of the piping. The valve gear ofthe tool 150 is not shown. A spring 155 is supported on the frame 70 andprovides a buffer for the calking tool 152. An inlet 158 is connectedwith a tube not shown to furnish the tool 150 with its air or otheroperating fluid.

To show the adaptability of the machine to various diameters of piping,large piping 20 is shown in Figs. 1, 2 and part of Fig. 3, a fragmentaryportion 160 of smaller piping is represented in part of Fig. 3 andpiping 161 of still smaller diameter is shown in Figs. 4, 5 and 6.

To operate the machine the track comprising the quadrants 22, 23, 24, 25is located in position around the piping, locking the pin 46 with thenose 49 and taking up lost motion by means of the screws 32. The chainhaving the links 133 is brought around the piping with the ends thereofengaged by the eyes 132 of the rack 130. The adjusting air cylinder 103is placed in proper operative position on its seat 99 and held in placeby the bracket 101, while the guide flanges 115, 119 respectivelyregister with the guides 71 and 72. The end of the yarn 146 is drawnfrom the spool 145 and brought against the outer edge of the calkingchisel 152. rllhe operator by means of air from the air inlet pipe 107moves the piston 110 in a position to locate the calking tool 150 inproper position, to press the yarn 146 into the annular chamber betweenthe bell and spigot end of the piping to be calked. While the chisel 152is reciprocating the operator, by means of the handle and theintervening elements turns the sprocket chain wheel 58, which revolvesthe truck frame 70, air cylinder 103, automatic calking tool 150 andtheir appurtenances around the piping. The combined reciprocations ofthe chisel 152 and the revolutions thereof around the piping locate theyarn in proper position between the spigot end and bell of the piping.The operator next pulls the end of the lead wool 144 from the spool 143and locates it in place in a manner similar to that described for theyarn, when the calking will be completed, the piston 110 being moved therequisite distance toward the cylinder head 104, so that the chisel 152when reciprocating will force the lead wool in place. To adjust themachine for different diameters of piping the guide rollers 87 areplaced in different operative positions, by locating the bolts 85 in therequisite openings in the ribs 77 and 80. To vary the angle of thechisel 152, the bolt 98 is placed in the different openings of the ribs94 and 96. By locating the piston 110 of the cylinder 103 in differentpositions enables the chisel 152 to reciprocate in different positionsin the annular space at the joint between the bell and spigot ends ofthe Plpmg.
